BTW, makes me recall another thing we have seen:
Some UAs actually do
two auths against the DB every time a registration arrives. Once for the
first INVITE (which receives an "auth required") and then another time
with a new nonce. I think it has something to do with the UA including
the old credentials in the first INVITE even though the nonce has
expired and an auth must be done to verify that the credentials are
incorrect. Have you seen this behavior?
g-)
Yes, I've seen this once but can't remember which client it was. IMO it
is a good idea to include the credentials (from the last nonce) in all
requests. If the nonce is still valid, this avoids the second request
with the credentials. On the other hand, it increases traffic on the
authentication servers. Don't know whats better :-)
